This Small Business Innovation Research (SBIR) Phase I project will develop a transformative green building technology that overcomes several limitations endemic to building automation systems in use today. Mainly, (a) the high cost of tethered sensor deployment, (b) the dependence on building energy, (c) the inaccuracy of occupancy sensors, and (d) the inability to adjust to changes in building usage over time. This project will utilize advanced wireless sensing technology to create a low-cost sensing platform that can be used to pervasively monitor building occupancy, environment, and energy consumption. These wireless sensors will then be embedded within a novel piezoelectric flooring system, which will provide power to the network using energy harvested from building foot traffic. By programming each wireless sensor with pattern classification capabilities, the resulting flooring system will be leveraged as an extremely accurate occupancy sensor. Lastly, by applying market-based optimization and reinforcement learning strategies, the resulting wireless smart floor itself will be designed to make optimal building control decisions in the midst of changing occupancy.The broader impact/commercial potential of this project centers around the improved and reliable implementation of wireless sensing and energy harvesting technologies within the built environment. While these technological benefits can be applied to a wide range of societal problems, this project is focused on maximizing the environmental and economic impact of green building automation technology. In the United States, commercial buildings have been documented to consume upwards of 18% of the Nation?s total energy and 35% of the Nation?s electricity. This is due in large part to the inefficient use of energy (e.g., the lighting, heating or air conditioning of unoccupied spaces). It has been found that green building technologies like the those being developed in this project have the potential to reduce annual U.S. commercial building energy consumption by roughly 6%, mitigating the environmental consequences of wasted energy while creating a green building market that could grow to nearly $150 billion by 2013. This project aims to capitalize on the potential economic and environmental impact of green building technologies by providing a self-powered wireless smart flooring system that can minimize unnecessary energy expenditure while providing building occupants with an additional level of comfort and environmental control.

这项小型企业创新研究（SBIR）I阶段项目将开发一种变革性的绿色建筑技术，该技术克服了当今使用的自动化系统特有的几个局限性。 （a）束缚传感器部署的高成本，（b）对建筑能源的依赖，（c）占用传感器的不准确性，以及（d）无法适应随着时间的推移构建使用情况的变化。该项目将利用先进的无线传感技术来创建一个低成本的传感平台，该平台可用于监视建筑物的占用，环境和能源消耗。然后，这些无线传感器将嵌入到新颖的压电地板系统中，该系统将使用从建筑物流量中收获的能量为网络提供动力。通过将每个无线传感器编程具有模式分类功能，将利用所得的地板系统作为非常准确的占用传感器。最后，通过采用基于市场的优化和强化学习策略，将设计的无线智能地板本身旨在在不断变化的占用情况下做出最佳的建筑控制决策。该项目的更广泛的影响/商业潜力围绕在建筑环境中改善和可靠的无线传感和能源收集技术实施。尽管这些技术益处可以应用于广泛的社会问题，但该项目的重点是最大程度地提高绿色建筑自动化技术的环境和经济影响。在美国，已记录了商业建筑物，可消费全国18％的总能源和全国35％的电力。这在很大程度上是由于能量的效率低下（例如，无人空间的照明，加热或空调）。已经发现，像该项目中开发的绿色建筑技术一样，有可能将年度美国商业建筑能源消耗降低大约6％，减轻浪费能源的环境后果，同时创造一个绿色建筑市场，到2013年，到2013年，该项目可能会增长到近1500亿美元。该项目旨在通过为绿色的能力实现绿色的潜在能力而实现绿色的能力，以实现绿色的能力，从而实现绿色的能力，以实现绿色的能力，以实现绿色的能力实现，并实现了自我实现的范围，而无需实现绿色的能力，并实现了自我实现的范围，并实现了自我实现的范围，并实现了自我实现的范围，而无需实现绿色的能力，则可以实现绿色的能力，并实现了良好的实现，并实现了良好的实现，并实现了自我实现的范围。为建筑物的乘员提供额外的舒适度和环境控制水平。
